Yeah, sometimes it takes more time as expected, depending on CD system overload… Especially boost is a huge library with many versions supported, and for 3 platforms with different compilers… Pre-building takes time.

If you are in a hurry, make a local copy of the recipes repo and install it from local filesystem, should work the same way.

Thanks for the tip, @Enhex, that was helpful. I made the PR, which will resolve the issue.

@Enhex @madduci @TheStormN it would be great, if you could test my patch on your machine, but I think everything should work great.
